What's the cause of cancellations in our spectra?¶

Spectra evolving with dephasing¶

Difference of absolute values of individual spectra¶

Look at cosine of phase difference¶

$$ I\propto \omega^2\lvert j_{inter} + j_{intra}\rvert = \omega^2\left[\lvert j_{inter}\rvert^2 + \lvert j_{inter}\rvert^2 + 2|j_{inter}||j_{intra}|\cos(\phi_{inter} - \phi_{intra})\right] $$

Is it actually a power law?¶

Look at phases¶

Phase of total velocity¶

Zoom in¶

Phase difference¶

Now again with zero padding¶
